A fired former University of Cincinnati police officer whose first trial for the murder of an unarmed black motorist ended in a mistrial earlier this month will be retried, prosecutors in Ohio said on Tuesday.

Body-camera video of the July 2015 incident showed then-officer Ray Tensing, 27, shooting Samuel DuBose, 43, in the head during a traffic stop after pulling DuBose over for a missing front license plate on his vehicle.

Hamilton County Prosecutor Joe Deters told a news conference in Cincinnati he would also seek a new venue for the retrial.

"After careful consideration, I have decided that the Tensing case will be retried. The decision was made after review of the trial transcript, discussion with some of the jurors and consultation with my staff," Deters said in a written statement.

"I am very hopeful that a second jury will be able to reach a decision to bring justice in this case for the victim's family and our community."

A jury of six white men, four white women and two black women failed on Nov. 12 to reach a verdict on whether Tensing was guilty of charges of murder and voluntary manslaughter, prompting the judge to declare a mistrial.

DuBose's killing fueled demonstrations against the use of lethal force by white officers against unarmed black people and other minorities, an issue that has been the focus of nationwide protests and a national debate over racial bias in the criminal justice system.

During the traffic stop near the southeast edge of the University of Cincinnati's main campus, Tensing asked DuBose to remove his seatbelt and tried to open the car door.

DuBose did not comply and closed the door. The vehicle started rolling forward slowly as Tensing pulled his gun and fired once.

Tensing was fired from the University of Cincinnati Police Department after being indicted in July 2015. He pleaded not guilty and was released on $1 million bond.
